Prosecutors are demanding Wesley Snipes' bail is revoked and the movie star is sent to prison immediately for failing to file tax returns.On Friday (16Jul10) officials in an Atlanta, Georgia appeals court upheld a judge's decision to put Snipes behind bars for three years on federal tax charges. No date for the Blade star's surrender was discussed and the correctional facility where Snipes, who has been free on bail pending the outcome of the appeal, would serve his time hasn't been revealed. On Wednesday (21Jul10), prosecutors filed a motion opposing Snipes' bail, stating, "There is no good reason to delay his surrender". The star's attorney, Daniel Meachum, insists he will respond to the filed documents soon. A jury originally convicted Snipes on three misdemeanour counts of wilful failure to file his income tax returns in 2008.
